HTMX and related libs work just fine as offline apps. I've been doing it with my personal apps I make for myself for a long time.

Also, morphdom/idiomorph get you a long way even when you have highly interactive pages, especially if you have to hit the back end anyways. If you don't need to hit the back end then a front end lib is fine. But even then, the simpler pattern of hypermedia-driven applications can be better.

See https://github.com/jon49/Soccer as an example of this.
